Yes, those same issue HAVE been mentioned year after year after year; but here is the very sad truth: Guys on sites like OS, discussing Madden 11 and getting hyped up for the next release or angry about previous year's shortcomings represent a VERY SMALL percentage of the overall Madden buying audience.
You are talking about at most 10% of the total install base each year and this is a game that sells in the millions annually (Let's just say 5,000,000 across all platforms) - and sadly as large as OS is, there are not 500,000 people checking out these threads! While we here and at other Internet communities want very specific changes to certain things, even in this protective bubble we can't agree amongst ourselves as to what is most important - witness the annual threads / flame wars discussing equipment and shoes and towels and presentation versus the replies that howl to fix the damn game before the bells and whistles are addressed.
When the Community Days are held and the feedback is taken I believe that EA wants to try to serve two opposing masters - the casual 90% of their customers - who buy Madden and play it from August to November and then get lost in the annual rush of Holiday season games - and the 10%'ers like this audience and others like it that want something much deeper and much more satisfying for the months after November and up to the next August.
These are opposing forces and we lack the numbers to get final say. Community days are an effort to soothe these sites and to gather feedback that is considered (and if it is economical and beneficial and in line with the overall marketing plan) and MAY get included at some point in the future. But when a game sells millions of copies year after year, the financial motivation to add a ton of programmers, break the code in untold hundreds of ways and risk the entire product launch is simply not there.
The devs want to try. The hard-core audience wants to play and wants to help. But in the end, the bean-counters and the suits rule the day and sign the checks and set the calenders. If an addition is causing problems that jeopardize the annual release date, it is going to be cut - and if the problem is significant enough that it would continue to break the game unless the overall package was revamped into something nearly unrecognizable in comparison to the previous year (or years), then you can rest assured it is not going to happen.
